Poisson regression for longitudinal data

Dear all,

I use the generalized linear model module to estimate a Poisson regression
in SPSS. (Potential) problem: The data represent an interrupted time series
(one country, 30 observations). Is it possible to adjust the standard errors
for the fact that the observations won't be independent - if so, how could
this be done in SPSS?

As an alternative, I thougt about using an autoregressive model (including
the predictors at t-1), but I am not sure whether this would yield adequate
standard errors?

Best, N.
